- 21unit impulse (unit sample) sequence is also called _________Dirac Delta
- 22unit step sequence is also called ________Heaviside Function
- 23Unit ramp sequence is also called ___________Ramp Function
- 24the signal is increases as n increasesRamp Sequence
- 25flipped signal is same with the original signalEven Signal
- 26flipped signal is the same with the reversed signalOdd Signal
- 27y[n] = x[n-k]TIme Shifting
- 28x[-n] is what operation on sequenceFlipping/Folding
- 29y[n] = x[an]time scaling

Addition - 37Discrete system is refers to a system that operates on discrete or _____ dataSampled
- 38Described as an operator _____ that takes sequence x[n] called _____ and transforms into other sequence y[n] called ______T[.]
Excitation
Response - 39What is "T" means in t[x[n]]Transform
- 40Discrete System is classified into:Linear System
Non-Linear system - 41It is a system that if you apply scaled version of an input signal, the output will also be scaled by the same factorLinear system
- 42relationship between inputs and outputs is not proportionalNon-linear
- 43linear discrete system is denoted as _______L[.]
- 44The discrete system is said to be linear if it satisfies __________Superposition Principle
- 45This principle states that if you have linear discrete system and you apply multiple input signals to that system separately, the overall response is the sum of the individual responses to each inputSuperposition Principle
- 46in this system input-output relationship doesn't vary with time when signal shifted advanced or delayLTI system
- 47this is the type of filter that is usually used in DSPKernel
- 48it provide impulse response of an LTI system and input relation to their outputConvolution
- 49it modifies the signal of the LTI systemImpulse response
